I was taking a look inside because I thought my touchpad cable might be loose, but I found this small plastic (what appears to be) piece of heatshrink floating around in an empty ram slot. I can’t find where it’s supposed to go and and I don’t see any wires shorting or anything, but I don’t like extra pieces.
Here’s a pic of the tube in question (with a screwdriver for scale)
On a separate note, are there canonical high-detail pictures of the inside of the case just for part/repair reference? The pictures from the repair guides aren’t super helpful, I’d like one “map” as it were.
